This Maintenance Release requires NetBackup 7.5 or higher be installed before applying.

For additional information about new platform proliferations, new features
associated with this release, end-of-life notifications, known issues, and
the current Maintenance Release content, refer to the following TechNote on the
Symantec Support Web site:

Before installing this Maintenance Release, please review the following items:

- Symantec recommends that you perform catalog backups before and after you
apply this Maintenance Release.

- If upgrading a NetBackup client on which this Maintenance Release has been
installed to a NetBackup server, you must first uninstall this Maintenance
Release, perform the upgrade from client to server, then re-apply this
Maintenance Release to the new server.

To install this Maintenance Release in a UNIX Cluster Environment:

1) Before you install this Maintenance Release, make sure that NetBackup is at
release level 7.5 and configured to run in a cluster.

2) Offline the cluster by following the procedures outlined in the
"NetBackup Clustered Master Server Administrator's Guide."

3) Freeze the cluster by following the procedures outlined in the
"NetBackup Clustered Master Server Administrator's Guide."

4) Install this Maintenance Release on the inactive node(s) of the cluster
first. (Perform the steps in the, "To install this Maintenance Release as
root on the NetBackup Server" procedure).

5) Install this Maintenance Release on the active node of the cluster.
(Again, perform the steps in the, "To install this Maintenance Release as
root on the NetBackup Server" procedure).

6) Unfreeze the cluster by following the procedure outlined in the "NetBackup
Clustered Master Server Administrator's Guide."

7) Online the cluster by following the procedures outlined in the
"NetBackup Clustered Master Server Administrator's Guide.

8) If the cluster is in a faulted state, clear the fault.

NOTE: A directory "NB_CLT_7.5.0.6" is created in the cluster shared
directory. This directory contains files that are needed during an
uninstall. Do not remove it.

NOTE: Selecting the client Maintenance Release on a Master/Media server
automatically installs the server Maintenance Release if the server (NB)
.gz file and README exist in the installation directory. The client install
fails if the (NB) .gz file and README are not present and the server release
has not been previously installed. The server Maintenance Release is NOT
installed automatically during a reinstall of the client Maintenance Release.

NOTE: The installation of the client Maintenance Release on a server copies
the appropriate client binaries into place on the server. Additionally,
any other 7.5 client binaries on the server are updated so that they
can then be pushed out using update_clients. If other client binaries are
installed after applying this Maintenance Release, this Maintenance Release
needs to re-run to patch those other client binaries.

NOTE: It is important that Server and Client binaries are kept at the same
release level on all NetBackup Servers. This is enforced by the install
process.

3) The NB_update.install script may prompt you to restart the daemons. Otherwise,
after the Maintenance Release installation has completed, run:

/usr/openv/netbackup/bin/bp.start_all

You can find the Maintenance Release install logs in
/usr/openv/pack/pack.history after the installation is complete.

4) Update the remote NetBackup clients with the update_clients script.

Note: The /usr/openv/netbackup/bin/update_clients command without
any parameters updates all the UNIX clients.

If the client (CLT) .gz file and README exist in the installation directory
during the installation of the server Maintenance Release, the
NB_update.install script installs the client Maintenance Release
automatically. The client Maintenance Release is NOT installed
automatically during a reinstall of the server Maintenance Release.

----------------

To perform a Local client install of this Maintenance Release:

NOTE: The install script determines if a local client install is appropriate
and chooses the appropriate client type to install.

Note: This will ONLY uninstall the Maintenance Release from your machine if the
client Maintenance Release software was installed directly on the machine.
This uninstall procedure will NOT work on clients that were installed
by pushing the software from a server.
